Syntax

'Declaration
Public Function GetExports(Of T) ( _
    contractName As String _
) As IEnumerable(Of Lazy(Of T))

public IEnumerable<Lazy<T>> GetExports<T>(
    string contractName
)

Type Parameters

  • T
    The type of the Export<T> objects to return.

Parameters

  • contractName
    Type: System.String
    The contract name of the Export<T> objects to return, or nulla null reference (Nothing in Visual Basic) or an empty string ("") to use the default contract name.

Return Value

Type: System.Collections.Generic.IEnumerable<Lazy<T>>
The Export<T> objects with the specified contract name, if found; otherwise, an empty ExportCollection<T> object.

Exceptions

Exception Condition
ObjectDisposedException

The CompositionContainer object has been disposed of.

Remarks

The returned Export<T> objects are instances of Export<T, TMetadataView> underneath, where TMetadataView is IDictionary<TKey, TValue>, TKey is String, and TValue is Object.

The default contract name is the result of calling the GetContractName method on T.

The contract name is compared by using the Ordinal property to perform a case-sensitive, non-linguistic comparison.
